Honeywell 01781 Indoor Outdoor Thermometer 12.5 in

Product Description

The HONEYWELL 01781 is a 12.5-inch diameter dial thermometer designed for indoor and outdoor temperature monitoring. It uses a coil-movement mechanism to display readings across a wide range of -60 degrees F to 120 degrees F. The molded plastic case and plastic lens provide weather resistance suitable for exposed installations. The large dial face is easy to read at a distance, making it practical for mounting in locations where frequent close inspection is not convenient. Pool service professionals, HVAC technicians, and facility maintenance staff commonly use thermometers like this to monitor ambient conditions at equipment locations, mechanical rooms, or outdoor service areas.

The 01781 is suited for residential and light commercial applications where a simple, reliable ambient temperature reference is needed without electronic components or batteries. Typical install locations include patios, gardens, yards, pool equipment enclosures, and garage or workshop walls. No wiring or power source is required, which makes installation straightforward in virtually any environment.

Installation Notes

Mount to a flat wall or post surface using standard fasteners through the rear mounting provision. For accurate readings, avoid positioning the thermometer in direct sunlight or directly above a heat-generating surface, as radiant heat will skew the reading. No electrical work is involved, so no power shutoff is required prior to installation.
